"Michelle was great. Very detail oriented, knowledge, and gave great suggestions during the post-purchase inspection. She allowed us to accompany her during the inspection and answered any and all questions we had, very approachable. She spent almost two hours with us and gave a great, 22 page report with photos afterwards. Good communication pre and post inspection. Highly recommend, I have already sent her info to a friend who is looking for an inspection."

Energy Efficiency Auditing FAQs, answered by experts

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

You can increase your home’s load factor by replacing fuse boxes with a circuit breaker, hiring a licensed electrician to upgrade your electrical panel, upgrading wiring, or installing subpanels. An electrical inspection by an expert can help determine the state of your current electrical systems and how they can be improved.

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.

Upgrade to double-glazed glass or apply energy-efficient coatings to reduce heat loss and utility costs.
